Y sizrriienrf ...Alipnatigninfirmerie, 1921.3 serial ivo-.ascesa Be, it lrnown that L Fn'rnn y'Kiainisiiirn aercitizen of the United States, residing at New VYOrk, in the county or" Bronx'and State of New Yorln` have invented' certain new vand, useful Improvements in Skylights, ofwhieh thev following is a full, clear,` and' exact ,sp'eciicatiom e p 1 This invention relates 'to skylights, and has for its object to provide' an: improved and simplied construction wherein the glass is supported securely fin proper position,

leakage isprevented and' previsioni is" made Y for Ventilating the building through the skylight. Y l

A' special object is toprovide a gutter of `improved construction which;perinitsfy the y Y external discharge offany wat'erfthat*pene` trates kthe skylight and alsofserves as means for' supporting thel glassmother Yspecial Objectistofsimplify and improve the eon'struction of the` ribs whichsupport and cover the lateral edges or' the glass.

g The invention lwill:befurther hereinafter described in connection withl the accoinpanyf e Y ing drawings which constitute parteil this specification, and then more specifically ydelinedfin the claims at the end of thel 'deA scriptio'n.` V
